Re: [ARSCLIST] Ampex & Sticky Shed Syndrome
When did Ampex get their patent? Patents in the US are for 20 years, I
believe, so even if they were inclined to enforce it, they can't have
many years left.

I wonder why the IEEE Transactions on Magnetics September 1982 paper
"Kinetics of Humid Aging of Magnetic Recording Tape" by H. Neal
Bertram
(Ampex) and Edward F. Cuddihy (JPL) wasn't referenced in the Ampex
Patent.
It is available online at
http://home.flash.net/~mrltapes/bertram_humid-aging.pdf
It is also widely listed on the Web in bibliographies.
Enjoy.
Cheers,
